Abstract

"PROCESSOS PARA USAR UMA ESTAçãO DE COMUNICAçãO MóVEL EM UMA REDE DE COMUNICAçãO SEM FIOS PARA MEDIR RESPECTIVOS TEMPOS DE CHEGADA DE SINAIS DE RáDIO RESPECTIVAMENTE TRANSMITIDOS POR UMA PLURALIDADE DE TRANSMISSORES DE RáDIO NA REDE, PARA LOCALIZAR A POSIçãO DE UMA ESTAçãO DE COMUNICAçãO MóVEL EM UMA REDE DE COMUNICAçãO SEM FIOS, E PARA DETERMINAR O TEMPO DE CHEGADA DE UM SINAL DE RáDIO EM UMA ESTAçãO DE COMUNICAçãO DE RáDIO QUE OPERA EM UMA REDE DE COMUNICAçãO SEM FIOS, E, APARELHOS PARA USO NA LOCALIZAçãO DA POSIçãO DE UMA ESTAçãO DE COMUNICAçãO MóVEL EM UMA REDE DE COMUNICAçãO SEM FIOS, E PARA MEDIR O TEMPO DE CHEGADA DE UM SINAL DE RáDIO NELE". Uma estação de comunicação móvel (MS 1) dentro de uma rede de comunicação sem fios é usada para medir os tempos respectivos de chegada de sinais de rádio transmitidos respectivamente por uma pluralidade de transmissores de rádio (23, 28) na rede. A estação de comunicação móvel é provida com informação de diferença de tempo real indicativa (RTDs) de diferenças entre uma base de tempo (60) usada por um transmissor de rádio (23) servindo a estação de comunicação móvel e bases de tempo respectivas usadas pelo outros transmissores de rádio. A estação de comunicação móvel determina, em resposta à informação de diferença de tempo real e relativa à base de tempo usada pelo transmissor de rádio que serve a estação de comunicação móvel, uma pluralidade de pontos em tempos aos quais os sinais de rádio respectivos são esperados chegarem na estação de comunicação móvel. Para cada sinal de rádio, a estação de comunicação móvel monitora chegada do sinal de rádio durante um período de tempo depois do ponto em tempo ao qual o sinal de rádio é esperado chegar."PROCESSES FOR USING A MOBILE COMMUNICATION STATION IN A WIRELESS COMMUNICATION NETWORK TO MEASURE THEIR RADIO SIGNAL ARRIVAL TIMES TRANSMITTED THROUGH A PLACE OF RADIO TRANSMITTERS ON THE NETWORK, TO LOCATE A LOCATION IN A POSITION. WIRELESS COMMUNICATION NETWORK, AND TO DETERMINE THE ARRIVAL TIME FOR A RADIO SIGNAL AT A RADIO COMMUNICATION STATION THAT OPERATES IN A WIRELESS COMMUNICATION NETWORK, AND, APPLIANCES FOR USE IN THE LOCATION OF A STATION POSITIONING STATION. IN A WIRELESS COMMUNICATION NETWORK, AND TO MEASURE THE ARRIVAL TIME OF A RADIO SIGNAL ON IT ". A mobile communication station (MS 1) within a wireless communication network is used to measure the respective arrival times for radio signals transmitted respectively by a plurality of radio transmitters (23, 28) on the network. The mobile communication station is provided with indicative real time difference information (RTDs) of differences between a time base (60) used by a radio transmitter (23) serving the mobile communication station and respective time bases used by the other radio transmitters. The mobile communication station determines, in response to the real time difference information and relative to the time base used by the radio transmitter serving the mobile communication station, a plurality of points at times at which the respective radio signals are expected. arrive at the mobile communication station. For each radio signal, the mobile communication station monitors the arrival of the radio signal for a period of time after the point in time at which the radio signal is expected to arrive.
